.... When pH-levels decline, a stream is said to have lost its acid neutralizing capacity (ANC). Aquatic and semi-aquatic animals, such as fish and salamanders, are more prone to stress and disease when exposed to acidity and heavy metals. As a remedy for acid stomach, people reach for Tums, or a similar ca...
